So I have come to a conclusion but of course it has to be proven right or wrong.
I know that there is good and bad bacteria in a fish tank. A fish tank can be to clean at times which can cause you fish to get sick. I started thinking, Bettas and most fish need that good bacteria in their tanks, but for what reason? Well, maybe it helps build up their immune system, or helps with their slime coat? Either way it helps them so they do not get sick as often. I don't really know that much about tank cycling, or things like that.
But this is just a thought that came to me when I was making a video for my YouTube channel on what not to do when cleaning a fish tank.
What do you guys think? Do you think in some way it does help? Has it already been proven? Give me your hypothesis.
It might be silly but I just wanted to ask...
